When Driving; Switches and Controls- Page 172



When the wiper lever is in the 
position and the ignition is switched ON,
the wipers may move automatically in
the following cases:



If the windshield above the rain sensor
is touched or wiped with a cloth.



If the windshield is struck with a hand
or other object from either outside or
inside the vehicle.

Keep hands and scrapers clear of the
windshield when the wiper lever is in the

 position and the ignition is

switched ON as fingers could be pinched
or the wipers and wiper blades damaged
when the wipers activate automatically.
If you are going to clean the windshield,
be sure the wipers are turned off
completely (when it is most likely that the
engine is left running) this is particularly
important when clearing ice and snow.

NOTE



Switching the auto-wiper lever from the

 to the 

 position while driving

activates the windshield wipers once,
after which they operate according to
the rainfall amount.



The auto-wiper control may not operate
when the rain sensor temperature is
about 

－

10 °C (14 °F) or lower, or

about 85 °C (185 °F) or higher.



If the windshield is coated with water
repellent, the rain sensor may not be
able to sense the amount of rainfall
correctly and the auto-wiper control
may not operate properly.



If dirt or foreign matter (such as ice or
matter containing salt water) adheres to
the windshield above the rain sensor, or
if the windshield is iced, it could cause
the wipers to move automatically.
However, if the wipers cannot remove
this ice, dirt or foreign matter, the
auto-wiper control will stop operation.
In this case, set the wiper lever to the
low speed position or high speed
position for manual operation, or
remove the ice, dirt or foreign matter by
hand to restore the auto-wiper
operation.



If the auto-wiper lever is left in the 
position, the wipers could operate
automatically from the effect of strong
light sources, electromagnetic waves, or
infrared light because the rain sensor
uses an optical sensor. It is
recommended that the auto-wiper lever
be switched to the 

 position other

than when driving the vehicle under
rainy conditions.



If the headlight switch and the
windshield wiper switch are in 

,

and the wipers are operated at low or
high speed by the auto wiper control for
several seconds, bad weather conditions
are determined and the headlights may
be turned on.



The auto-wiper control functions can be
turned off. Refer to Personalization
Features on page 9-9.
